So far so good. One screw and the back plate is off. You can see the battery clip which I never use. I'll probably leave it in place, but I'm not concerned about being able to access it in my new enclosure since I'll be running off of a power supply...
Four little screws and the first board is out. It has the input and output jacks and the power input, all of which I intend to replace. It is connected to the other board by a little white clip with wires which you can see I unplugged. The knobs for adjusting the effects are attached to potentiometers on the board that is still in place. Those knobs are just press fit in place, so you need to carefully pull them off before you can remove the other board. I wrapped my t-shirt around them and used a pair of pliers and the came off with too much trouble.
A few more screws and everything comes apart. Here's the whole thing minus the original housing. You can see the three knobs and their corresponding pots. In the lower left corner is the super wimpy momentary switch that operates the effect. The button part is built into the original plastic housing, but I intend to replace that with a beefier switch anyway. The gum-wrapper looking thing is a piece of foil shielding they had wrapped around the board with the pots.
So that is the easy part. Next I'll start work on the new enclosure and try and track down wiring diagrams on the internet to proceed to phase two. Then I can really cause some damage.
